Y=-x^2 is a perfectly valid and understandable equation tho

Edit: I completely misunderstood, the line is how you should read it lol

Unless I'm reading it wrong thats exactly what they did, hire a third party, external agency to conduct an investigation. If the complaint is that it's biased because they paid them, then idk what else you wanted them to do. I could understand not fully trusting them still, that's your opinion and choice, but criticizing them for conducting a voluntary third party investigation is a little silly

Yeah I'm not sure what the point about the moon waste is considering it's likely inside the remainins of lunar landers. The real space junk to worry about is all the stuff in LEO that will cause problems with satellites and such in the near future

Heres my analysis of what all has actually happened from a similar post with this article yesterday

From reading through the article and it's sources, here's what seems to be the case:

  • a simulation at Berkely National Labs with their supercomputing capabilities has verified that LK-99 theoretically has superconducting properties

  • Argonne National Labs also seems to be involved and doing stuff, but nothing official from them yet, besides maybe helping with simulation stuff

  • a Russian scientist is working on improving the synthesis process and has made some low purity samples that produce the Messnier effect, but higher purity than the original I think. It's all from Twitter (x) threads and a little hard to follow. Her handle is @iris_IGB

  • China National Lab (Shenyang) first principles analysis suggest gold and silver doping LK-99 will make superconductors as well. [Directly copied from article]

  • Under the guidance of Professor Chang Haixin, postdoctoral Wu Hao and doctoral student Yang Li of the School of Materials Science and Technology of Huazhong University of Science and Technology they have successfully verified and synthesized the LK-99 crystal. It can be magnetically levitated for the first time and this is shown on a bilibili video. They expect to realize the true sense of non-contact superconducting magnetic levitation. [Also Directly copied from article]

I would give LK-99 a 95 percent chance of either being a true rook temperature superconductor or directly leading to the discovery of a true rook temp superconductor in the next few years.

A few caveats however: according to the simulation, the conductive pathways only forms when the copper bonds to a specific higher-energy spot in the crystal, so getting higher purities will likely need a fair amount of innovation on the production process. There are some other complications with the synthesis, so even if it is fully and properly confirmed with more papers and such it will still likely be a while before it can start to be used effectively.

I would say with 95 percent confidence that: it's real bois!

Sometimes it will work after multiple presses, sometimes not at all. It may be a Lemmy or Lemmy.world problem, but if it's Voyager I'm on Android using firefox

KSP is finally starting to become reality! For those who haven't played, there is an equivalent engine in the game called the "Nerv" which functions on the same principle, and is an incredibly useful engine. It's cool to see this idea finally be developed into a real system

Another fun thing is that at 0,0 in the center of the canvas it said "Never forget what they stole from you r/save3rdpartyapps" and later had a join-lemmy.org banner above it. We also had a few other places for the join-lemmy banner but that was the final location, and a big thanks to the Black Company discord server for helping with that.

As some may have noticed, a fairly large portion of the post on this community are article links posted by bots. I am no moderator and am just a regular user like the rest of you, but I want to know what the community thinks of the posting bots. here is a sample of my opinion to get conversation started:

Pros:

  • lots of content to engage with
  • people can focus on discussing things not finding thing

Cons:

  • lack of reliable quality of article
  • lack of diversity of content

Btw for those wondering what is up with the post formatting, it's a post bot.

There are rings in the game that give you buffs, often in sets. The Ring of Rock gives +13 armor, the Ring of Stone gives +14 mining damage, and the set bonus gives +49 mining damage. I had seen that there would be a pair earlier, but i finally got the set and acheivement yesterday.

according to this the total land area of built up human development and infrastructure is also around 1%, seems a hell of a lot easier to mandate every building have a white roof. Especially considering most buildings have black roofs, it will be even more of a difference. Also will reduce energy consumption from AC because, as said in the article buildings panted with it have reduced need for cooling.

Roads could also maybe be painted or have a whiter material used, might make it harder to drive though

one thing i would be interested in seeing is what kinds of games are causing these problems. I would bet its mostly your mobile gatcha games, at least that kid running away from home must be. A lot of actual psycological research goes into making those games addictive, so no wonder they are addictive. Having actual stats to back it up tho would be nice and could maybe get some restrictions on them passed, especially lootboxes as is somewhat talked about in the article

I am about to go to college for engineering and they require a Windows laptop because of the software we will be using (mostly solidworks I'm pretty sure) doesn't work on other operating systems. I primarily use windows day-to-day for gaming and such anyways so it's not a problem for me but I'm wondering if anyone had experience using solidworks or any other industry-class CAD software like Inventor on linux
